.local domains very unreliable

[janfjohannes]

Describe the bug

.local domains stop working randomly especially after the containers run for a longer time. only solution is to restart docker compose, but this also is flaky

To Reproduce

use .local domains with docker compose with longer running containers

Expected behavior

.local domains should always work instant. there should be a setting to modify the dns cache or have some insights into what is happening.

No response

Please share a screenshot of the exact error message you're seeing when trying to connect to a domain that isn't working.

Also, a sample project to reproduce this would be helpful.

short update: it is more reliable to "fix" this problem by quitting orbstack and restarting orbstack than the containers, which might sometimes work and take a while to load on the first reload of the page, while quitting and restarting the orbstack application seems to make the domain resolve immediately after the restart. (screenshots comming asap)

unfortunately the issue reappeared

[janfjohannes]

my docker compose example is here, though it feels this is is happening to all my setups.
so far the issue appeared always after around 1 day the latest
(the "git" service is just an nginx standard image proxying to the gitea instance)

  git:
    restart: always

i could not 100% confirm sleep mode does have a connection, but it seems that dns failing is always reproducible after a longer time of sleep mode of the macbook

[janfjohannes]

@kdrag0n any updates on this? this is the last blocker from my perspective to introduce orbstack into my team at work and also buy licenses....

[kdrag0n]

We can't reproduce this unfortunately. It'd be great if you could figure out what's causing it, e.g. some network-related software / configs / VPNs / proxy or anything that could be interfering with the domains on your machine.

[janfjohannes]

@kdrag0n thanks :/ could you give me any starter to debug this? eg. how did you implement this? is this mDNS / zeroconf based? I think you support other endings besides .local which would not be possible in mDNS right? any terminal commands like dig i should use?

[janfjohannes]

this gets worse as much as i investigate. it also appears orbstack can mix up the urls of services very rarely, but enough to be potentially horrific. eg. service exp.local sometimes just resolves to git.local until orbstack is restarted!
